Montgomery Cunningham Meigs (/ˈmɛɡz/; May 3, 1816 – January 2, 1892) was a career United States Army officer and civil engineer, who served as Quartermaster General of the U.S. Army during and after the American Civil War. Meigs strongly opposed secession and supported the Union; his record as Quartermaster General was regarded as outstanding, both in effectiveness and in ethical probity, and Secretary of State William H. Seward viewed it as a key factor in the Union victory.
